Twelve precision measurement utilities for photos, camera feeds, blueprints, and digital screens — computed locally in your browser.
Measure distance, dimensions, angles, areas, and perimeters directly on uploaded or pasted photos with zoom, pan, and real-world calibration.
MeasurementCalibrate real-world scale from reference objects (credit cards, rulers, coins, doors) to measure true physical lengths in mm, cm, m, inches, and feet.
MeasurementActual size virtual on-screen ruler calibrated in centimeters, millimeters, and inches with standard credit card screen calibration.

MeasurementCalibrate real-world scale from reference objects (credit cards, rulers, coins, doors) to measure true physical lengths in mm, cm, m, inches, and feet.
MeasurementMeasure objects in real time using your phone or web camera with reference card alignment, freeze-frame inspection, and zero server uploads.
MeasurementInspect pixel distance, X/Y coordinates, bounding box width/height, and CSS dimensions on uploaded screenshots and web designs.
MeasurementActual size virtual on-screen ruler calibrated in centimeters, millimeters, and inches with standard credit card screen calibration.
MeasurementSet scale from known room dimensions or scale bars to measure room square footage, wall lengths, and total floor plan areas.
MeasurementMeasure architectural and engineering CAD blueprints with standard imperial and metric drafting scale ratios (1/4"=1', 1:50, 1:100).
MeasurementPhotographic on-screen protractor measuring 3-point vertex angles, acute, obtuse, and reflex angles, and slope degrees directly from photos.
MeasurementCalculate closed polygon surface area and perimeter from photos using Shoelace formula coordinates with calibrated sq m, sq ft, or sq cm output.
MeasurementMeasure circular objects, radius, diameter, arc, and circumference from photos using 3-point circular fitting and calibrated units.
MeasurementConvert physical and screen dimensions between millimeters, centimeters, meters, inches, feet, yards, and screen pixels at custom PPI/DPI.
MeasurementCalculate architectural and model scale ratios (1:X), dimension scaling factors, aspect ratios, and measurement tolerances.
MeasurementWhether inspecting architectural floor plans, verifying design pixel spacing, calibrating real-world object scales from photos, or measuring angles and dimensions with your phone camera, online measurement should be instant, reliable, and completely private.
NexLove Measurement Tools operate entirely inside your web browser using HTML5 Canvas, sub-pixel vector geometry, and client-side calibration algorithms. You can set physical scale using standard reference objects (like a credit card, coin, or door), measure polygons with the Shoelace formula, compute 3-point vertex angles, and calculate circle diameters with mathematical precision.
Your photos, floor plans, and camera feeds never leave your local device. Every tool runs offline-capable with zero cloud API keys, zero watermarks, and no registration required.
